Transmission
To communicate, all radios in your group must be set to the same channel.
Briefly press the Function key 1 to enable the Monitor feature that will
verify if the frequency is not busy, then press the PTT button.
Release the PTT key to receive.
Only one user at a time can talk during radio communications. Therefore, it is
important not to transmit when you are receiving a communication and use the
transmission mode sparingly to allow other users to talk.
Transmission consumes a significant amount of energy and should therefore be
used sparingly to prolong the battery life.
If you are unable to contact a station that you have no problems in receiving,
the station may be using CTCSS tones or DCS codes.
Monitor
The Monitor feature is for temporarily excluding (opening) the Squelch,
in order to listen to signals that are too weak to keep the Squelch perma-
nently opened.
Briefly press the Function key 1 to enable such function.
